PREFACE. 


THIS  book  has  been  issued  in  answer  to  a  repeated  call  fora 
simple  presentation  of  the  newer  statistical  methods  in  their 
application  to  biology.  The  immediate  need  which  has  called 
it  forth  is  that  of  a  handbook  containing  the  working  formulae 
for  use  at  summer  laboratories  where  material  for  variation  - 
study  abounds.  In  order  that  the  book  should  not  be  too 
bulky  the  text  has  been  condensed  as  much  as  is  consistent 
with  clearness. 

This  book  was  already  in  rough  draft  when  the  work  of 
Duncker  appeared  in  Roux's  Archiv.  I  have  made  much  use 
of  Duncker's  paper,  especially  in  Chapter  IV.  I  am  indebted 
to  Dr.  Frederick  H.  Safford,  Assistant  Professor  of  Mathe- 
matics at  the  University  of  Cincinnati  and  formerly  Instructor 
at  Harvard  University,  for  kindly  reading  the  proofs  and  for 
valuable  advice.  To  Messrs.  Keuffel  and  Esser,  of  New  York, 
I  am  indebted  for  the  use  of  the  electrotypes  of  Figures  1  and  2. 
Finally,  I  cannot  fail  to  acknowledge  the  cordial  cooperation 
which  the  publishers  have  given  in  making  the  book  ser- 
viceable.

PREFACE  TO  THE  SECOND  EDITION. 


THE  first  edition  of  this  book  having  been  favorably  re- 
ceived, the  publishers  have  authorized  a  revised  edition 
embodying  many  of  the  new  statistical  methods  elaborated 
chiefly  by  Professor  Karl  Pearson  and  his  students  and 
associates,  and  presenting  a  summary  of  the  results  gained 
by  these  methods.  These,  while  increasing  somewhat  the 
bulk  of  the  book,  have,  it  is  hoped,  rendered  it  more  service- 
able to  investigators.  Too  much  emphasis  can  hardly  be 
laid  on  the  debt  that  Biometricians  owe  to  Professor  Pear- 
son's indefatigable  researches  in  the  new  science  of  Biome- 
try— especially  in  the  development  of  Statistical  Theory. 

The  publishers,  also,  of  this  book  are  deserving  of  credit 
for  the  courage  they  have  shown  in  reproducing  expensive 
tables  for  the  use  of  a  still  very  limited  body  of  statistical 
workers.  Especial  attention  is  called  to  Table  IV,  which 
is  an  extension  of  Table  IV  of  the  first  edition  that  was  cal- 
culated by  Professor  Frederick  H.  Safford,  and  appears  to 
have  been  the  first  published  table  of  the  normal  probability 
integrals  based  on  the  standard  deviation.  More  recently 
Mr.  W.  F.  Sheppard  has  published  in  Biometrika  a  similar 
table  in  which,  however,  the  tabular  entries  are  given  to 
seven  places  of  decimals,  while  the  arguments  are  given 
to  two  decimal  places  only.  In  the  present  table  the  argu- 
ments are  subdivided  to  three  places  of  decimals  and  with 
the  aid  of  the  table  of  proportional  parts  interpolation  is 
easily  effected. 

Especial  acknowledgment  must  be  made  of  assistance 
received  from  my  friend  Mr.  F.  E.  Lutz,  who  read  over  the 
entire  manuscript  and  contributed  certain  of  the  numerical 
examples.

BIOLOGICAL   VAKIATION, 


CHAPTER  I. 

ON  METHODS  OF  MEASURING  ORGANISMS. 
Preliminary  Definitions. 

An  individual  is  a  segregated  mass  of  living  matter,  capable 
of  independent  existence.  Individuals  are  either  simple  or 
compound,  i.e.,  stocks  or  corms.  In  the  case  of  a  compound 
individual  the  morphological  unit  may  be  called  a  person. 

A  multiple  organ  is  one  that  is  repeated  many  times  on  the 
same  individual.  Example,  the  leaves  on  a  tree,  the  scales 
on  a  fish. 

A  character  is  any  quality  common  to  a  number  of  indi- 
viduals or  to  a  number  of  multiple  organs  of  one  individual. 

A  variate  is  a  single  magnitude-determination  of  a  character. 

Integral  variates  are  magnitude-determinations  of  charac- 
ters which  from  their  nature  are  expressed  in  integers.  Such 
magnitudes  are  expressed  by  counting;  e.g.,  the  number  of 
teeth  in  the  porpoise.  These  are  also  called  discontinuous. 

Graduated  variates  are  magnitude-determinations  of  char- 
acters which  do  not  exist  as  integers  and  which  may  conse- 
quently differ  in  different  variates  by  any  degree  of  magni- 
tude however  small;  e.g.,  the  stature  of  man. 

A  variant,  among  integral  variates,  is  a  single  number-con- 
dition, e.g.,  5  (flowers),  13  (ray-flowers),  etc. 

A  class,  among  graduated  variates,  includes  variates  of 
the  same  or  nearly  the  same  magnitude.  The  class  range 
gives  the  limits  between  which  the  variates  of  any  class  fall. 

Individual  variation  deals  with  diversity  in  the  characters 
of  individuals. 

Organ  variation,  or  partial  variation,  deals  with  diversity  in 
multiple  organs  in  single  individuals.

2  STATISTICAL   METHODS. 

Methods  of  Collecting  Individuals  for  Meas- 
urement. 

In  collecting  a  lot  of  individuals  for  the  study  of  the  varia- 
bility of  any  character  undue  selection  must  be  avoided.  The 
rule  is: 

Having  settled  upon  the  general  conditions,  of  race,  sex, 
locality,  age,  which  the  individuals  to  be  measured  must  fulfil, 
take  the  individuals  methodically  at  random  and  without  possible 
selection  of  individuals  on  the  basis  of  the  magnitude  of  the 
character  to  be  measured.  If  the  individuals  are  simply  not 
consciously  selected  on  the  basis  of  magnitude  of  the  character 
they  will  often  be  taken  sufficiently  at  random. 

The  number  of  variates  to  be  obtained  should  be  large;  if 
possible  from  200  to  2000,  depending  on  abundance  and 
variability  of  the  material. 

Processes  Preliminary  to  Measuring 
Characters. 

Some  characters  can  best  be  measured  directly;  e.g.,  the 
stature  of  a  race  of  men.  Often  the  character  can  be  better 
studied  by  reproducing  it  on  paper.  The  two  principal 
methods  of  reproducing  are  by  photography  and  by  camera 
drawings. 

For  photographic  reproductions  the  organs  to  be  measured 
will  be  differently  treated  according  as  they  are  opaque  or 
transparent.  Opaque  organs  should  be  arranged  if  possible 
in  large  series  on  a  suitable  opaque  or  transparent  back- 
ground. The  prints  should  be  made  on  a  rough  paper  so 
that  they  can  be  written  on ;  blue-print  paper  is  excellent. 
This  method  is  applicable  to  hard  parts  which  may  be  studied 
dry;  e.g.,  mollusc  shells,  echinoderms,  various  large  arthro- 
pods, epidermal  markings  of  vertebrates  and  parts  of  the 
vertebrate  skeleton.  Shadow  photographs  may  be  made  of 
the  outlines  of  opaque  objects,  such  as  birds'  bills,  birds'  eggs, 
and  butterfly  wings,  by  using  parallel  rays  of  light  and  inter- 
posing the  object  between  the  source  of  light*  and  the  photo- 

*  A  Welsbach  burner  or  an  electric  light  are  especially  good.    Minute

graphic  paper.  More  or  less  transparent  organs,  such  as 
leaves,  petals,  insect-wings,  and  appendages  of  the  smaller 
Crustacea,  may  be  reproduced  either  directly  on  blue-print 
paper  or  by  "solar  prints,"  either  of  natural  size  or  greatly 
enlarged.  For  solar  printing  the  objects  should  be  mounted 
in  series  on  glass  plates.  They  may  be  fixed  on  the  plate  by 
means  of  balsam  or  albumen  and  mounted  between  plates  either 
dry  or  in  Canada  balsam  or  other  permanent  mounting  media. 
Wings  of  flies,  orthoptera,  neuroptera,  etc.,  may  be  prepared 
for  study  in  this  way;  twenty-five  to  one  hundred  sets  of  wings 
being  photographed  on  one  sheet  of  paper,  say  16  X  20  inches 
in  size.  Microphotographs  will  sometimes  be  found  service- 
able in  studying  small  organisms  or  organs,  such  as  shells  of 
Protozoa  or  cytological  details. 

Camera  drawings  are  a  convenient  although  slow  method  of 
reproducing  on  paper  greatly  enlarged  outlines  of  microscopic 
characters,  such  as  the  form  and  markings  of  worms  and 
lower  Crustacea,  sponge  spicules,  bristles,  scales  and  scutes, 
plant- hairs,  cells  and  other  microscopic  objects.  In  making 
such  camera  drawings  a  low-power  objective,  such  as  Zeiss  A*, 
will  often  be  found  very  useful. 

The  Determination  of  Integral  Variates.— 
Methods  of  Counting. 

While  the  counting  of  small  numbers  offers  no  special  diffi- 
culty, the  counting  becomes  more  difficult  with  an  increase  of 
numbers.  To  count  large  numbers  the  general  rule  is  to  di- 
vide the  field  occupied  by  the  numerous  organs  into  many 
snail  fields  each  containing  only  a  few  organs.  Counting 
under  the  microscope,  e.g.,  the  number  of  spines,  scales  or 
plant-hairs  per  square  millimetre,  may  be  aided  by  cross-hair 
rectangles  in  the  eyepiece.  The  number  of  blood-corpuscles 
in  a  drop  of  blood,  or  of  organisms  in  a  cubic  centimetre  of 
water,  have  long  been  counted  on  glass  slides  ruled  in  small 
squares. 

electric  lamps  such  as  are  fed  by  a  single  cell  give  sharp  shadows  of 
small  objects. 


STATISTICAL   METHODS. 


The    Determination  of  Graduated   Variates,— 
Methods  of  Measurement. 

Straight  lines  on  a  plane  surface  are  easily  meas- 
ured by  means  of  a  measuring-scale  of  some  sort.  The  meas- 
urement should  always  be  metric  because 
this  is  the  universal  scientific  system.  Vari- 
ous kinds  of  scales  may  be  obtained  of 
optical  companies  and  hardware  dealers, — 
such  as  steel  measuring  tapes,  graduated  to 
millimetres  (about  $1.00),  and  steel  rules 
(6  cm.  to  15  cm. )  graduated  to  £  of  a  milli- 
metre. Steel  "spring-bow"  dividers  with 
milled-head  screw  are  useful  for  getting 
distances  which  may  be  laid  off  on  a  scale. 
Tortuous  lines,  e.g.,  the  contour  of  the 
serrated  margin  of  a  leaf  or  the  outer 
margin  of  the  wing  of  a  sphinx  moth,  may 
be  measured  by  a  map-measurer  ("Entfer- 
nungsmesser,"  Fig.  1),  supplied  at  artist's 
and  engineer's  supply  stores  at  about  $3.50. 
Distances  through  solid  bodies 
or  cavities  are  measured  by  calipers  of 
some  sort.  Calipers  for  measuring  diameters 
of  solid  bodies  are  made  in  various  styles. 
Micrometer  screw  calipers  ("  speeded") 
reading  to  one-hundredths  of  a  millimetre 
and  sold  by  dealers  in  physical  apparatus  for 
about  $5.00  are  excellent  for  determining  diameters  of  bones, 
birds'  eggs,  gastropod  shells,  etc.  Leg  calipers  for  rougher 
work  can  be  obtained  for  from  30  cents  to  $4.00.  The 
micrometer  "  caliper-square,"  available  for  inside  or  outside 
measurements  and  measuring  to  hundredths  of  a  millimetre, 
is  a  useful  instrument.* 

The  area  of  plane  surfaces,  as,  e.g.,  of  a  wing  or  leaf, 
is  easily  determined  by  means  of  a  sheet  of  colloidin  scratched 
in  millimetre  squares.  By  rubbing  in  a  little  carmine  the 

*  Many  of  the  instruments  described  in  this  section  are  made  by  the 
Starrett  Co.,  Athol,  Mass.,  and  by  Brown  and  Sharpe,  Providence,  tool 
cutters. 


FIG.  1.

scratches  may  be  made  clearer.  The  number  of  squares 
covered  by  the  surface  is  counted  (fractional  squares  being 
mentally  summated)  and  the  required  area  is  at  once  obtained. 
If  the  area  has  been  traced  on  paper  it  may  be  measured  by 
the  planimeter  (Fig.  2).  This  instrument  may  be  obtained  at

engineer's  supply  shops.  It  consists  of  two  steel  arms  hinged 
together  at  one  end;  the  other  end  of  one  arm  is  fixed  by  a 
pin  into  the  paper,  the  end  of  the  second  arm  is  provided  with 
a  tracer.  By  merely  tracing  the  periphery  of  the  figure  whose 
area  is  to  be  determined  the  area  may  be  read  off  from  a  drum 
which  moves  with  the  second  arm.  This  method  is  less 
wearisome  than  the  method  of  counting  squares. 

The  area  of  a  curved  surface,  like  that  of  the  elytra 
of  a  beetle  or  the  shell  of  a  clam,  is  not  always  easy  to  find. 
To  get  the  area  approximately,  project  the  curved  surface  on 
a  plane  by  making  a  camera  drawing  or  photograph  of  its 
outline.  By  means  of  parallel  lines  divide  the  outline  draw- 
ing into  strips  such  that  the  corresponding  parts  of  the  curved 
surface  are  only  slightly  curved  across  the  strips,  but  greatly 
curved  lengthwise  of  the  strips.  Measure  the  length  of  each 
plane  strip  and  divide  the  magnitude  by  the  magnification  of 
the  drawing.  Measure  also,  with  a  flexible  scale,  the  length 
of  the  corresponding  strip  on  the  curved  surface.  Then,  the 
area  of  any  strip  of  the  object  is  to  the  area  of  the  projection 
as  the  length  of  the  strip  on  the  object  is  to  the  length  of  its 
projection.  The  sum  of  the  areas  of  the  strips  will  give  the 
total  area  of  the  surface. 


6  STATISTICAL   METHODS. 

Characters  occupying  three  dimensions  of 
space  may  be  quantitatively  expressed  by  volume.  The 
volume  of  water  or  sand  displaced  may  be  used  to  measure 
volume  in  the  case  of  solids.  The  volume  of  water  or  sand  con- 
tained will  measure  a  cavity.  Irregular  form  is  best  measured 
by  getting,  either  by  means  of  photography  or  drawings,  pro- 
jections of  the  object  on  one  or  more  of  the  three  rectangular 
fundamental  planes  of  the  organ,  and  then  measuring  these 
plane  figures  as  already  described.  Or  two  or  more  axes  may 
be  measured  and  their  ratio  found. 

Characters  having  weight  are  easily  measured  ;  the 
only  precautions  being  those  observed  by  physicists  and 
chemists. 

Color  Characters.  Color  may  be  qualitatively  ex- 
pressed by  reference  to  named  standard  color  samples.  Sucl} 
standard  color  samples  are  given  in  Ridgeway's  book, 
"  Nomenclature  of  Color,"  and  also  in  a  set  of  samples  manu- 
factured by  the  Milton  Bradley  Co.,  Springfield,  Mass.,  costing 
6  cents.  The  best  way  of  designating  a  color  character  is  by 
means  of  the  color  wheel,  a  cheap  form  of  which  (costing  6 
cents)  is  made  by  the  Milton  Bradley  Co.  The  colors  of  this 
"top"  are  standard  and  are  of  known  wave-length  as  follows: 
Red,  656  to  661  Green,  514  to  519 

Orange,  606  to  611  Blue,     467  to  472 

Yellow,  577  to  582  Violet,  419  to  424. 

It  is  desirable  to  use  Milton  Bradley's  color  top  as  a  standard. 
Any  color  character  can  be  matched  by  using  the  elementary 
colors  and  white  and  black  in  certain  proportions.  The  pro- 
portions are  given  in  percents.  In  practice  the  fewest  possible 
colors  necessary  to  give  the  color  character  should  be  employed 
and  two  or  three  independent  determinations  of  each  should 
be  made  at  different  times  and  the  results  averaged.  So  far 
as  my  experience  goes  any  color  character  is  given  by  only 
one  least  combination  of  elementary  colors.  (See  Science, 
July  16,  1897.) 

When  there  is  a  complex  color  pattern  the  color  of  the 
different  patches  must  be  determined  separately.  In  case  of 
a  close  intermingling  of  colors,  the  colored  area  may  be  rapidly 
rotated  on  a  turntable  so  that  the  colors  blend  and  the  result- 


MEASUREMENT    OF    ORGANISMS.  7 

ant  may  then  be  compared  with  the  color  wheel.  By  this 
means  also  the  total  melanism  or  albinism,  viridescence,  etc., 
may  be  measured. 

Marking-Characters.  The  quantitative  expression  of 
markings  or  color  patterns  will  often  call  for  the  greatest 
ingenuity  of  the  naturalist.  Only  the  most  general  rules  can 
here  be  laid  down.  Study  the  markings  comparatively  in  a 
large  number  of  the  individuals,  reduce  the  pattern  to  its 
simplest  elements,  and  find  the  law  of  the  qualitative  variation 
of  these  elements.  The  variation  of  the  elements  can  usually 
be  treated  under  one  of  the  preceding  categories.  Find  in  how 
far  the  variation  of  the  color  pattern  is  due  to  the  variation  of 
some  number  or  other  magnitude,  and  express  the  variation  in 
terms  of  that  magnitude.  Remember  that  it  is  rarely  a  ques- 
tion whether  the  variation  of  the  character  can  be  expressed 
quantitatively  but  rather  what  is  the  best  method  of  express- 
ing it  quantitatively. 

Aids  in  Calculating1.  An  indispensable  aid  in  multi- 
plying and  dividing  is  a  book  of  reckoning  tables  of  which 
Crelle's  Rechnungstafeln  (Berlin:  Geo.  Reimer)  is  the  best. 
This  work  enables  us  to  get  directly  any  product  to  999  X  999 
and  indirectly,  but  with  great  rapidity,  any  higher  product  or 
any  quotient. 

The  tables  of  Barlow  ("  Tables  of  Squares,  Cubes,  Square 
Roots,  Cube  Roots,  and  Reciprocals  of  all  Integer  Numbers 
up  to  10,000")  are  like  our  Table  X,  but  more  extended. 

The  tedious  work  of  adding  columns  of  numbers  is  greatly 
simplified  by  the  use  of  some  one  of  the  better  adding  ma- 
chines. There  are  many  forms,  of  which  the  best  are  made 
in  the  United  States.  The  author  has  used  the  "  Comp- 
tometer" made  by  the  Felt  and  Tarrent  Manufacturing  Co., 
Chicago  ($125),  and  found  it  perfectly  satisfactory.  This 
machine  is  manipulated  by  touching  keys,  as  in  a  typewriter, 
but  it  does  not  print  the  numbers  touched  off.  In  this  respect 
it  is  inferior  to  the  Burroughs  Adding  Machine  of  the  Ameri- 
can Arithometer  Co.,  St.  Louis,  Mo.,  which  costs  $250  to  $350, 
or  to  the  Standard  Adding  Machine,  St.  Louis  ($185). 

For  the  multiplication  and  division  of  large  numbers  the 
Baldwin  Calculator  is  well  spoken  of  (Science,  xvn,  706).  It 
is  sold  by  the  Spectator  Company,  95  William  Street,  New 
York,  price  $250.  The  same  firm  is  agent  for  Tate's  Im-

proved  Arithometer  ($300  to  $400).  The  "Brunsviga"  cal- 
culating machine  (Herrn  Grimme,  Natalis  &  Co.,  Brunswick, 
Germany,  Manufacturers;  price  $140  to  & 75)  is  highly  recom- 
mended by  Pearson. 

To  draw  logarithmic  curves  and  for  the  mechanical  solu- 
tion of  arithmetical  problems  the  instrument  of  Brooks 
(Science,  xvn,  690,  not  yet  marketed)  should  be  found  useful. 

Precautions  in  Arithmetical  Work.  Even  the 
most  careful  computers  make  mistakes  in  arithmetical  work. 
It  is  absolutely  necessary  to  take  such  precautions  that  errors 
may  be  detected.  The  best  method  is  for  statistical  workers 
to  compute  in  pairs,  but  absolutely  independently,  comparing 
results  as  the  work  progresses,  so  that  time  shall  not  be 
wasted  by  elaborate  work  done  with  erroneous  values.  In 
case  of  disagreement  both  workers  should  recompute,  start- 
ing from  that  point  of  the  work  where  their  results  check.  In 
cases  where  it  is  not  feasible  for  the  work  to  be  done  by  two 
people,  it  should  be  calculated  on  distinct  pages  of  the  note- 
book— proceeding  through  several  steps  on  the  one  page  and 
then  independently  through  the  same  steps  on  another  page; 
checking  the  work  as  it  progresses.  It  will  be  found  useful 
as  the  work  progresses  to  make  rough  checks  by  comparing 
the  results  with  the  original  data  to  see  that  the  results  are 
probable. 

Neatness  in  arrangement  of  work  and  in  the  making  of 
figures  is  essential.  It  is  best  to  make  all  calculations  in  a 
book  with  pages  about  20  cm.  by  30  cm.,  quadruple  ruled, 
with  about  three  squares  to  the  centimetre,  so  that  each 
figure  may  occupy  a  distinct  square.  I  like  to  work  with  a 
pencil,  of  2H  grade,  so  that  slight  errors  may  be  erased  and 
rectified.  In  case  of  larger  errors  running  through  several 
steps  of  the  work,  the  erroneous  calculations  should  not  be 
erased  but  cancelled. 

In  using  logarithms  with  the  six-place  table  given  in  this 
book,  it  is  ordinarily  necessary  to  write  the  entire  mantissa 
to  six  places,  and  to  determine  the  number  corresponding  to 
any  logarithm  to  at  least  six  places  by  use  of  the  table  of 
proportional  parts  given  at  the  bottom  of  the  page.  Upon 
the  completion  of  the  calculation  the  number  of  decimal 
places  cO  be  recorded  will  depend  upon  the  probable*  error  of 


MEASUREMENT   OF   ORGANISMS.  9 

each  constant.  It  will  ordinarily  suffice  if  the  probable  error 
contain  two  significant  figures,  e.g.,  ±0.17  or  ±0.0089;  then 
the  constant  will  be  carried  out  to  the  same  number  of  places 
and  not  farther.

CHAPTER  II. 

ON  THE  SERIATION  AND  PLOTTING  OP  DATA  ANJD  THE 
FREQUENCY  POLYGON. 

The  data  obtained  by  measuring  any  character  in  a  lot  of 
individuals  consists  either  of  amass  of  numbers  for  the  charac- 
ter in  each  individual ;  or,  perhaps,  two  numbers  which  are  to 
be  united  to  form  a  ratio  ;  or,  finally,  a  series  of  numbers  such 
as  are  obtained  by  the  color  wheel,  of  the  order  :  TF40#,  N 
(Black)  38#,  7  12$,  Q  101  The  first  operation  is  the  simplifi- 
cation of  data.  Each  variate  must  be  represented  by  one 
number  only.  Consequently,  quotients  of  ratios  must  be  de- 
termined and  that  single  color  of  a  series  of  colors  which  shows 
most  variability  in  the  species  must  be  selected,  e.g.,N. 

The  process  of  seriation,  which  comes  next,  consists  of  the 
grouping  of  similar  magnitudes  into  the  same  magnitude 
class.  The  classes  being  arranged  in  order  of  magnitude, 
the  number  of  variates  occurring  in  each  class  is  determined. 
The  number  of  variates  in  the  class  determines  the  frequency 
of  the  class.  Each  class  has  a  central  value,  an  inner  and  an 
outer  limiting  value,  and  a  certain  range  of  values. 

The  method  of  seriation  may  be  illustrated  by  two  examples  ;  one  of 
integral  variates,  and  the  other  of  graduated  variates. 

Example  1.  The  magnitude  of  21  integral  variates  are  found  to  be  as 
follows  :    12, 14,  11,  13,  12,  12,  14,  13,  12,  11,  12,  12,  11,  12,  10,  11,  12,  13,  12, 
13,  12, 12.    In  seriation  they  are  arranged  as  follows  : 
Classes:        10,11,12,13,14. 
Frequency :    1,    4,  11,    4,    2. 

Example  2.  In  the  more  frequent  case  of  graduated  variates  our  mag- 
nitudes might  be  more  as  follows  : 

3.2  4.5  5.2  5.6  6.0 
3.8           4.7           5.2           5.7  6.2 
4.1           4.9           5.3           5.8  6.4 

4.3  5.0  5.3  5.8  6.7 
4.3           5.1           5.4           5.9           7.3 

In  this  case  it  is  clear  that  our  magnitudes  are  not  exact,  but  are  merely 
approximations  of  the  real  (forever  unknowable)  value.  The  question 


SERIATIO^   AND    PLOTTING    OF    DATA.  11 

arises  concerning  the  inclusivencss  of  a  class — the  cZa.ss  range.  An 
approximate  rule  is  :  Make  the  classes  oni}-  just  large  enough  to  have 
no  or  very  few  vacant  classes  in  the  series.  Following  this  rule  we  get 

Classes 

Frequency 
Classes.... 

Frequency 

The  classes  are  named  from  their  middle  value,  or  better,  for  ease  of 
subsequent  calculations,  by  a  series  of  small  integers  (1  to  9). 

In  case  the  data  show  a  tendency  of  the  observer  towards  estimating 
to  the  nearest  round  number,  like  5  or  10,  each  class  should  include  one 
and  only  one  of  these  round  numbers. 

As  Fechuer  ('97)  has  pointed  out,  the  frequency  of  the  classes  and  all 
the  data  to  be  calculated  from  the  series  will  vary  according  to  the 
point  at  which  we  begin  our  seriation.  Thus  if,  instead  of  beginning  the 
series  with  3.0  as  in  our  example,  we  begin  with  3.1  we  get  the  series  : 


3.0-3.4;

which  is  quite  a  different  series.  Fechner  suggests  the  rule:  Choose  such 
a  position  of  the  classes  as  will  give  a  most  normal  distribution  of  fre- 
quencies. According  to  this  rule  the  first  distribution  proposed  above 
is  to  be  preferred  to  the  second. 

In  order  to  give  a  more  vivid  picture  of  the  frequency  of 
the  classes  it  is  important  to  plot  the  frequency  polygon. 
This  is  done  on  coordinate  paper.* 

The  best  method,  especially  when  the  number  of  classes 
is  less  than  20,  is  to  represent  the  frequencies  by  rectangles 
of  equal  base  and  of  altitude  proportional  to  the  frequencies. 
Lay  off  along  a  horizontal  line  equal  contiguous  spaces  each 
of  which  shall  represent  one  class,  number  the  spaces  in  order 
from  left  to  right  with  the  class  magnitudes  in  succession, 
and  erect  upon  these  bases  rectangles  proportionate  in  height 
to  the  frequency  of  the  respective  classes  (Fig.  3).

STATISTICAL   METHODS. 


This  method  of  drawing  the  frequency  polygon  is  known  as 
the  method  of  rectangles. 

When  the  number  of  classes  is  large  the  frequencies  may  be 
represented  by  ordinates  as  follows :   At  equal  intervals  along

nates whose  successive  heights  shall  be  proportional  to  the 
frequency  of  the  classes.  Join  the  tops  of  the  ordinates  as 
shown  in  Fig.  4.  This  method  of  drawing  the  frequency 
polygon  is  known  as  the  method  of  loaded  ordinates.

The  rejection  of  extreme  variates  in  calculating 
the  constants  of  a  distribution  polygon  is  to  be  done  only 
rarely  and  with  caution.  In  many  physical  measurements 
Chauvenet's  criterion  is  used  to  test  the  suspicion  that  a 
single  extreme  variant  should  be  rejected.  A  limiting  devia- 
tion (KG)  is  calculated.  K  is  the  argument  in  Table  IV  cor- 
responding to  a  tabular  entry  equal  to  — - —  •

Looking  in  Table  IV  we  find  3.48  corresponding  to  the  entry  49975. 
Then  the  limiting  deviation  =  3.  48  X.  728  =  2.5334  and  the  limiting  class 
is  10.835  —  2.533=8.302;  hence  the  observation  at  7  might  be  excluded 
in  calculating  the  constants  of  the  seriation  ;  but  it  should  not  be  sup- 
pressed in  publishing  the  data. 

CERTAIN  CONSTANTS  OF  THE  FREQUENCY  POLYGON. 

After  the  data  have  been  gathered  and  arranged  it  is  neces- 
sary to  determine  the  law  of  distribution  of  the  variates.  To 
get  at  this  law  we  must  first  determine  certain  constants. 

The  average  or  mean  (A)  is  the  abscissa  of  the  centre  of 
gravity  of  the  frequency  polygon.  It  is  found  by  the  formula 


in  which  V  is  the  magnitude  of  any  class;  /  its  frequency; 
I  indicates  that  the  sum  of  the  products  for  all  classes  into 
frequency  is  to  be  got,  and  n  is  the  number  of  variates. 

Thus  in  the  example  on  p.  10: 
A  =(3.2X1+3.7X1+4.2X3-1-4.7X3  +  5.2X7+5.7X5+6.2X3 

+  6.7  XI  +7.2  XI)  -^25  =  5.24, 
or 

AI  =  (IX  1+2  XI  +3X3  +4X3  +5X7  +6X5  +7X3+8X1+  9X1) 

-*-  25=5.08, 
A  =5.2*  +  .08(5.7  -5.2)  =5.24.  ' 

A  still  shorter  method  of  finding  A  is  given  on  page  20. 

The  mode  (M)  is  the  class  with  the  greatest  frequency. 
It  is  necessary  to  distinguish  sharply  between  the  empirical 
and  the  theoretical  mode.  The  empirical  mode  is  that  mode 
which  is  found  on  inspection  of  the  seriated  data.  In  the 
example,  the  empirical  mode  is  5.2.  The  theoretical  mode  is 
the  mode  of  the  theoretical  curve  most  closely  agreeing  with 
the  observed  distribution.  Pearson  1902b,  p.  261)  gives  this 

*  5.2  is  the  true  class  magnitude  corresponding  to  the  integer  5, 


14  STATISTICAL   METHODS. 

rule  for  roughly  determining  the  theoretical  mode.  The 
mode  lies  on  the  opposite  side  of  the  median  from  the  mean  ; 
and  the  abscissal  distance  from  the  median  to  the  mode  is 
double  the  distance  from  the  median  to  the  mean;  or, 
mode=mean  —  3  X  (mean  —  median).  More  precise  directions 
for  finding  the  mode  in  the  different  types  of  frequency  poly- 
gons are  given  in  the  discussion  of  the  types. 

The  median  magnitude  is  one  above  which  and  below 
which  50%  of  the  variates  occur.  It  is  such  a  point  on  the 
axis  of  X  of  the  frequency  polygon  that  an  ordinate  drawn 
from  it  bisects  the  polygon  of  rectangles  or  the  continuous 
curve,  but  not  the  polygon  of  loaded  ordinates. 

To  find  its  position:  Divide  the  variates  into  three  lots:  those  less  than 
the  middle  class,  i.e.,  the  one  that  contains  the  median  magnitude,  of 
which  the  total  number  is  a;  those  of  the  middle  class,  b;  and  those 
greater,  c.  Then  a  +  b  +  c  =  n  —  the  total  number  of  variates:  Let  V  = 
the  lower  limiting  value  of  the  middle  class,  and  I"  =  the  upper  limiting 
value,  and  let  x  =  the  abscissal  distance  of  the  median  ordinate  above  the 
lower  limit  or  below  the  upper  limit  of  the  median  class  according  as  x 
is  positive  or  negative.  Then  \n  —  a  :  b  =  x  :  I"  —  I'  when  x  is  positive, 
or  \n  —  c  :  b  =  x  :  I"  —  V  when  x  is  negative. 

Thus  in  the  last  example:  (12.5-8):  7=x  :  0.5;  #=.32;  the  median 
magnitude  =  5.0  +  .32  =  5.  32.  Or  (12.5-10):  7  =  -x  :  0.5;  x=-.18\ 
the  median  magnitude  =5.  5  -.18  =  5.  32.  (Cf.  p.  10.) 

The  probable  error  (E)  of  the  determination  of 

any  value  gives  the  measure  of  unreliability  of  the  determina- 
tion; and  it  should  always  be  found.  For,  any  determination 
of  a  constant  of  a  frequency  polygon  is  only  an  approximation 
to  the  truth.  The  probable  error  (E)  is  a  pair  of  values  lying 
one  above  and  the  other  below  the  value  determined.  We 
can  say  that  there  is  an  even  chance  that  the  true  value  lies 
between  these  limits.  The  chances  that  the  true  value  lies 
within  :* 

±2#are    4.5:1  ±5E  are      1,310:1 

±3Eare21     :1  ±6E  are    19,200:1 

±  4E  are  142  :  1  ±  7E  are  420,000  :  1 

iCEare  17,000,000:1 

are  about  a  billion  to  1. 


The   probable   error   should  be  found  to   two   significant

SERIATIOK    AND    PLOTTING    OF    DATA.  15 

figures.  The  determination  of  which  it  is  the  error  should 
be  carried  out  to  the  same  number  of  places  as  the  probable 
error  and  no  more. 

The  probable  difference  between  two  averages  (A1  and 
A  2)  of  which  the  probable  errors  (El  and  E2)  are  known  is 
the  square  root  of  the  sum  of  the  squared  probable  errors,  or 
(Pearson,  '02): 

Probable  Difference  ot  A,-A2  is  \/E*  +  E*. 

The  probable  error  of  the  menu  is  given  by  the 
formula

It  will  be  seen  that  the  probable  error  is  less,  that  is,  that 
the  result  is  more  accurate,  the  greater  the  number  of  variates 
measured,  but  the  accuracy  does  not  increase  in  the  same  ratio 
as  the  number  of  individuals  measured,  but  as  the  square  root 
of  the  number.  The  probable  error  of  the  mean  decreases  as 
the  standard  deviation  decreases. 

The_  probable  error  of  the  median  is  ±.84535(7 
-7-Vn  (Sheppard,  '98). 

The  geometric  mean  of  a  series  of  values  (v)  is  the 
number  corresponding  to  the  average  of  the  logarithms  of 
the  values.  Thus, 


The  index  of  the  variability,  a,  of  the  variates  when 
they  group  themselves  about  one  mode  is  found  by  adding 
the  products  of  the  squared  deviation-from-the-mean  of  each 
class  multiplied  by  its  frequency,  dividing  by  the  total 
number  of  variates,  and  extracting  the  square  root  of  the 
quotient,  thus: 


sum  of  [(deviation  of  class  from  mean)2 

X  frequency  of  class]

whore  A  is  the  number  of  units  in  the  class  range,  frequently 
unity. 


16  STATISTICAL    METHODS. 

This  measure  is  known  as  the  standard  deviation.  It 
is  a  concrete  number  expressed  in  the  units  of  the  classes. 
This,  the  best  measure  of  variability,  is  expressed  geomet- 
rically as  the  half  parameter,  or  the  abscissa  of  the  point  on 
the  frequency  curve  where  the  change  of  curvature  (from 
concave  to  convex  toward  the  centre)  occurs. 

The  probable  error  of  the  standard  deviation  is

Other  Indices  of  Variation.  The  average  deviation, 
or  average  departure,  is  found  thus: 

.  j.  ^sum  of  [deviations  of  class  from  mean  X  frequency] 
number  of  variates 

The  average  deviation  is  equal  to  .7 97 9  X  standard  deviation,  or 
-0.7979*. 

The  probable  (or  mid)  departure  is  the  distance  from  the  mode 
of  that  ordinate  which  exactly  bisects  the  half  curve  OMX  or  OMX} , 
Fig.  5,  it  is  equal  to  0.6745  X  standard  deviation  =  0.6745*7.  Neither 
of  these  last  two  indices  of  variation  is  as  good  as  the  standard  devia- 
tion when  n  is  rather  small. 

The  standard  deviation,  like  the  other  indices  of  variation, 
is  a  concrete  number,  being  expressed  in  the  same  units  as 
the  magnitudes  of  the  classes.  The  standard  deviation  of 
one  lot  of  variates  is  consequently  not  comparable  with  the 
S.  D.  of  variates  measured  in  other  units.  It  has  been  pro- 
posed to  reduce  the  index  of  variation  to  an  abstract  number, 
independent  of  any  particular  unit,  by  dividing  the  index  of 
variation  of  any  variates  by  the  mean;  the  quotient  multi- 
plied by  100  is  called  the  coefficient  of  variability.  In 

a  formula,  C=-j-XlOO%  (Pearson,  '96;    Brewster,  '97). 
A. 

The  probable  error  of  the  coefficient  of  vari- 
ability is  given  by  Pearson  as: 


SERIATIOK   AND    PLOTTING    OF    DATA.  17 

When  C  is  small,  say  less  than  10%,  the  factor  in  brackets 
may  be  omitted,  especially  as  only  two  significant  figures 
of  the  probable  error  need  be  recorded* 

The  average,  standard  deviation,  coefficient  of  correlation, 
and  their  probable  errors  may  be  conveniently  calculated  al- 
together by  logarithms,  as  shown  in  the  paradigm  on  page  38. 

QUICK  METHODS  OF  ROUGHLY  DETERMINING  AVERAGE  AND 
VARIABILITY.* 

1.  Arrange  the  specimens  in  a  series  according  to  the  mag- 
nitude of  the  character,  simply  judging  the  order  by  the  eye. 
Then  pick  out  those  two  that  will  divide  the  series  into  thirds 
and  measure  them.  Their  average  will  be  the  average  of  the 
whole  series.  Then, 

Mean  —  the  smaller  of  the  two  measures

o 

included  between  these  limits  of  x  equals  one-third  of  the 
whole)  . 

Or,  2.  Select  roughly  two  specimens  that  seem  to  be  about 
one-third  of  the  distance  from  the  two  extremes  £nd  group 
all  others  as  larger  than  the  larger  one,  smaller  than  the 
smaller  one,  or  between  the  two.  Measure  the  two  speci- 
mens. Count  the  number  in  each  group  and  determine  a 
by  aid  of  Table  IV  (p.  120)  as  follows:  Taking  as  origin  the 
middle  of  the  whole  series,  call  the  number  of  leaves  from 
the  middle  to  the  smaller  n/,  and  the  number  from  the 
middle  to  the  larger  n2".  Also,  the  x  distance  to  the  lower 
division  point  /^  and  to  the  upper  division  point  h2.  Then 
(/ij-|-/&2)  =  the  range  covered  by  the  middle  division  or  the 
difference  between  the  upper  and  lower  value.  As  we  know 
the  areas  of  the  curve  between  the  origin  and  /^  on  the  one 
hand  and  h2  on  the  other  (percentage  of  individuals  between 

the  middle  and  ht  and  h2),  we  can  find  —  and  —  from  Table  IV,

Or  the  value  of  the  character  of  the  middle  specimen  may 
be  taken  as  the  mean  value. 

EXAMPLE. — Seventy-six  beech-leaves  which  had  fallen  from  one 
tree  were  picked  up.  They  were  sorted  out  as  in  the  second  method. 
It  was  found  that  22  were  smaller  than  the  smaller  type  leaf,  which 
was  1.78  inches  in  length;  and  23  were  larger  than  the  larger  type  leaf 
(2.22  inches  in  length).  The  38th  leaf  is  the  middle  of  the  series,  and 
so  the  smaller  type  leaf  was  distant  16  laaves  from  the  middle,  and 
the  larger  15.

THE    CLASSES    OF    FREQUENCY    POLYGONS.          19 


CHAPTER  III. 
THE  CLASSES  OF  FREQUENCY  POLYGONS. 

The  plotted  curve  may  fall  into  one  of  the  following  classes : 

A.  Unimodal. 

I.  Simple. 

1.  Range  unlimited  in  both  directions: 

a.  Symmetrical.     The  normal  curve. 

b.  Unsym metrical  (Pearson's  Type  IV). 

2.  Range  limited   in  one    direction,    together    with 

skewness  (Types  III,  V,  and  VI). 

3.  Range  limited  in  both  directions  : 

a.  Symmetrical,  Type  II. 

b.  Unsymmetrical,  Type  I. 
II.  Complex. 

B.  Multimodal. 

The  classification  of  any  given  curve  is  not  always  an  easy 
task.  Whether  the  curve  is  unimodal  or  multimodal  can  be 
told  by  inspection.  Whether  any  unimodal  curve  is  simple 
or  complex  cannot  be  told  by  any  existing  methods  without 
great  labor  and  uncertainty  in  the  result. 

Complex  curves  may  be  classified  as  follows  : 

1.  Composed  of  two  curves,  whose  modes  are  different  but  so  near  that 
the  component  curves  blend  into  one  ;   such  curves  are  usually  unsym- 
metrical. 

2.  The  sum  of  two  curves  having  the  same  mode  but  differing  varia- 
bility. 

3.  The  difference  of  two  curves  having  the  same  mode  but  differing 
variability. 

If  the  material  is  believed  to  be  homogeneous  and  the  curve 
is  unimodal  it  is  probably  simple  and  its  classification  may  be 
carried  further. 

For  classification  the  rule  is  as  follows :  Determine  the  mean 
of  the  magnitudes.  Take  a  class  near  the  mean  (call  it  F0) 


20  STATISTICAL   METHODS. 

as  a  zero  point ;  then  the  departure  of  all  the  other  classes 
will  be  -  1,  -  2,  -  3,  etc.,  and  +  1,  -f  2,  -f  3,  etc. 

Add  the  products  of  all  these  departures  multiplied  by  the 
frequency  of  tbe  corresponding  class  and  divide  by  n;  call 
the  quotient  rt. 

Add  the  products  of  the  squares  of  all  the  departures  multi- 
plied by  the  f-requency  of  the  corresponding  class  and  divide 
by  n\  call  the  quotient  v^. 

Add  the  products  of  the  cubes  of  all  the  departures  multiplied 
by  the  frequency  of  the  corresponding  class  and  divide  by  n\ 
call  the  quotient  r3. 

Add  the  products  of  ih&fourtfi  powers  of  all  the  departures 
multiplied  by  the  frequency  of  the  corresponding  class  and 
divide  by  ?i;  call  the  quotient  r4.  Or,

known,  A  may  be  found  [A  =  1 


The  values  rlf  r9t  ra,  v4,  are  called  respectively  the  first, 
second,  third,  and  fourth  moments  of  the  curve  about  Fo. 

To  get  the  moments  of  the  curve  about  the  mean,  either  of 
two  methods  (A  or  B)  will  be  employed.  Method  A  is  used 
when  integral  variates  are  under  consideration  ;  method  B 
when  we  deal  with  graduated  variates. 

(A)  To  find  moments  in  case  of  integral  variates: 


*  This  is  the  short  method  of  finding  A  referred  to  on  page  13.

THE  NORMAL  CURVE. 

The  normal  curve  is  symmetrical  about  the  mode;  con- 
sequently the  mode  and  the  median  and  mean  coincide. 
The  mathematical  formula  of  the  normal  curve,  a  formula 


much  used.     jFi  =  2/?2  —  3ft  —  6.     The  classification  was  given  as  follows: 

/?i>0,  curve  is  of  Type  I. 

Pi  =0,  /?2<3,  curve  is  of  Type  II. 

/?i>  0,  /?2>  3,  curve  is  of  Type  III. 

ft  =0,  ,52  =  3,  curve  is  normal. 
When  F  is  positive  and  ft  >  0,  32>  3,  curve  is  of  Type  IV.

This  formula  gives  the  value  of  any  ordinate  y  (or  any  class) 
at  any  distance  x  (measured  along  the  base,  X,  X',  of  Fig.  5) 
from  the  mode,  e  is  a  constant  number,  2.71828,  the  base 
of  the  Naperian  system  of  logarithms,  n  is  the  total  area 
of  the  curve  or  number  of  variates,  and  a  is  the  Standard 
Deviation,  which  is  constant  for  any  curve  and  measures  the 
variability  of  the  curve,  or  the  steepness  of  its  slope. 

To  compare  any  observed  curve  with  the  theo- 
retical normal  curve  we  can  make  use  of  tables.  For 
the  case  of  a  polygon  of  loaded  ordinates  the  theoretical  fre- 

x 
quency  of  any  class  at  a  deviation  —  from  the  mean  can  be 

taken  directly  from  Table  III.     Here  —  is  the  actual  devia- 
tion from  the  mean  expressed  in  units  of  the  standard  devia- 

tion, and  —  the   corresponding  ordinate,   y0  being  taken  as 

2/o 
equal  to  1,  and  a  is  the  standard  deviation. 

For  the  case  of  a  polygon  built  up  of  rectangles  represent- 
ing the  relative  frequency  of  the  variates,  Table  IV  gives 
immediately  the  theoretical  number  of  individuals  occurring 

between  the  values  x=Q  and  x=  ±—.     By  looking  up  the 
given  values  of  —  the  corresponding  theoretical  percentage 

of  variates  between  the  limits  x=0  and  x=  db—  will  be  found 

a 

directly.     The  ratio  —  may  be  called  the  Index  of  Abmodality. 

The  normal  curve  may  preferably  be  employed  even  when 
&  is  not  exactly  equal  to  0,  nor  /?2  exactly  equal  to  3,  nor  F 
exactly  equal  to  0.  Use  the  normal  curve  when

To  determine  the  closeness  of  fit  of  a  theoreti- 
cal polygon  to  the  observed  polygon.  Find  for 
each  class  the  difference  (<^)  between  the  theoretical  value  (y} 
and  the  observed  frequency  (/).  Divide  the  square  of  this 
difference  in  each  case  by  y.  The  square  root  of  the  sum  of  the

The  probability  (P:l)  that  the  observed  distribution  is  truly 
represented  by  the  theoretical  polygon  may  be  calculated  from 
the  following  formula,  to  use  which  the  number  of  classes 
(A)  must  be  odd  or  must  be  made  odd  by  the  addition  of  a 
class  with  0  frequency. 


This  is  the  method  of  Pearson,  1900&.

actual  discrepancy.  The  probable  discrepancy  should  next  be 
calculated  for  all  but  the  extreme  values.  It  is  calculated

OTHER  UNIMODAL  FREQUENCY  POLYGONS. 
The  formulas  of  Pearson's  Types  I  to  VI  are  as  follows: 

Type     I.  ,= 

Type    II.  y= 

TypellL  y=y0    l  +  j          */<*. 

Type  IV.  y=y0cos62me-*e,  where  tan  0=j. 

Type    V.     y=yQx-pe-r/x. 

Type  VI.    y=y0(x-l)^/x^. 

In  these  formulas: 
x,  abscissae; 
2/0,  the  ordinate  at  the  origin,  to  be  especially  reckoned  for 

each  type; 
y,  the  height  of  the  ordinate  (or  rectangle)  located  at  the 

distance  x  from  2/0; 
I,  a  part  of  the  abscissa-axis  XX'  expressed  in  units  of  the 

classes; 
<?,  the  base  of  the  Naperian  system  of  logarithms,  2.71828. 

The  other  letters  stand  for  relations  that  are  explained  in 
the  sections  below  treating  of  each  type  separately. 

The  range  of  the  curve  is  limited  in  both  directions  in 
Types  I  and  II,  is  limited  in  one  direction  only  in  Types  III, 
V,  and  VI,  and  is  unlimited  in  both  directions  in  Type  IV 
and  the  normal  curve.  The  normal  curve  may  give  the  best 
fit,  however,  notwithstanding  the  fact  that  in  biological 
statistics  the  range  is  ordinarily  limited  at  both  extremes. 
Thus  the  range  of  carapace  length  to  total  length  of  the 
lobster  is  limited  between  0  and  1.  The  ratio  of  carapace 
length  to  abdominal  length  in  various  crustaceans  may,  how- 
ever, conceivably  take  any  value  from  -f  oo  to  0.  In  the  ratio 
of  dorsoventral  to  aiitero-posterior  diameter  the  forms  of  the 
molluscan  genera  Pinna  or  Malleus  on  the  one  hand  and 
Solen  on  the  other  approach  such  extremes.

separated  from  each  other  by  a  certain  distance  D;  or  D  = 
mean  —  mode.  Asymmetry  is  measured  by  the  ratio  a=  —  . 

If  the  mean  is  greater  than  the  mode,  skewness  is  positive; 
if  the  mean  is  less  than  the  mode,  skewness  is  negative.  D, 
and  hence  skewness,  may  be  calculated  when  the  theoretical 
mode  is  known  (see  pages  13,  14,  and  below). 

In  Types  I  and  III  skewness  is    measured  also  by  the

MULTIMODAL   CURVES. 

Multimodal  curves  are  given  when  the  frequency  in  the 
different  classes  exhibits  more  than  one  mode.  False  mul- 
timodal  curves  result  from  too  few  observations,  or  when  the 
classes  are  too  numerous  for  the  variates.  By  increasing  the 
number  of  variates  or  by  making  the  classes  more  inclusive 
some  of  the  modes  disappear. 

*  Tn  degrees  and  fractions  of  a  degree;    see  Table  VII. 


40  STATISTICAL   METHODS. 

Multimodal  curves  differ  in  degree.  The  modes  may  be  so 
close  that  only  a  single  mode  (usually  in  an  asymmetrical 
curve)  appears  in  the  result;  or  one  of  the  modes  may  appear 
as  a  hump  on  the  other;  or  the  two  modes  may  even  be  far 
apart  and  separated  by  a  deep  sinus  (Figs.  7  to  10).

FIG.  7. 

Pearson  has  offered  a  means  of  breaking  up  a  compound 
curve  with  apparently  only  one  mode  into  two  curves  having 
distinct  modes;  but  this  method  is  very  tedious  and  rarely 
applicable. 


FIG.  8.

components.* 

The  index  of  isolation  of  two  masses  of  variates 
grouped  about  adjacent  modes  is  the  ratio  of  the  depression 
between  the  modes  to  the  height  of  the  shorter  mode. 

The  meaning  of  multimodal  curves  is  diverse.     Sometimes

they  indicate  a  polymorphic  condition  of  the  species,  the  modes 
representing  the  different  type  forms.     This  is  the  case  with

species  into  two  or  more  varieties. 

*  I  have  proposed  (Science,  VII,  685)  to  measure  the  divergence  in  a

CORRELATED  VARIABILITY. 

Correlated  variation  is  such  a  relation  between  the  magni- 
tudes of  two  or  more  characters  that  any  abmodality  of  the 
one  is  accompanied  by  a  corresponding  abmodality  of  the 
other  or  others. 

The  methods  of  measuring  correlation  given  below  are 
applicable  to  cases  where  the  distribution  of  variates  is 
either  symmetrical  or  skew. 

The  principles  upon  which  the  measure  of  correlated  varia- 
tion rests  are  these.  When  we  take  individuals  at  random  we 
find  that  the  mean  magnitude  of  any  character  is  equal  to  the 
mean  magnitude  of  this  character  in  the  whole  population. 
Deviation  from  the  mean  of  the  whole  population  in  any  lot  of 
individuals  implies  a  selection.  If  we  select  individuals  on 
the  basis  of  one  character  (A ,  called  the  subject)  we  select  also 
any  closely  correlated  character  (B,  called  the  relative)  (e.g., 
leg-length  and  stature).  If  perfectly  correlated,  the  index  of 
abmodality  (p.  23)  of  any  class  of  B  will  be  as  great  as  that  of 
the  corresponding  class  of  A ,  or 

Index  abmodality  of  relative  class 
Index  abmodality  of  subject  class  = 

If  there  is  no  correlation,  then  whatever  the  value  of  the 
index  of  abmodality  of  the  subject,  that  of  the  relative  will 
be  zero  and  the  coefficient  of  correlation  will  be 

Index  of  abmodality  of  relative  class  _   0  _ 
Index  of  abmodality  of  subject  class       m  ~~ 

The  coefficient  of  correlation  is  represented  in  formulas  by 
the  letter  r.  We  cannot  find  the  degree  of  correlation  be- 
tween two  organs  by  measuring  a  single  pair  only;  it  is  the 
correlation  "in  the  long  run"  which  we  must  consider. 
Hence  we  must  deal  with  masses  and  with  averages.

44  STATISTICAL   METHODS. 

In  studying  correlation  one  (either  one)  of  the  characters  is 
regarded  as  subject  and  the  other  as  relative.  A  correlation 
table  is  then  arranged  as  in  the  example  on  page  43,  which 
gives  data  for  determining  the  correlation  between  the  num- 
ber of  Miillerian  glands  on  the  right  (subject)  and  left  (rela- 
tive) legs  of  male  swine.  The  selected  subject  class  is  called 
the  type;  the  corresponding  distribution  of  the  relative  mag- 
nitudes is  called  the  array. 

METHODS  OP  DETERMINING  COEFFICIENT  OF  CORRELATION. 

Gallon's  graphic  method.  On  co-ordinate  paper 
draw  perpendicular  axes  JTand  T\  locate  a  series  of  points 
from  the  pairs  of  indices  of  abmodality  of  the  relative  and  sub- 
ject corresponding  to  each  subject  class.  The  indices  of  the 
subjects  are  laid  off  as  abscissae  ;  the  indices  of  the  relatives 
as  ordinates,  regarding  signs.  Get  another  set  of  points  by  mak- 
ing a  second  correlation  table,  regarding  character  B  as  subject 
and  character  A  as  relative.  Then  draw  a  straight  line  through 
these  points  so  as  to  divide  the  region  occupied  by  them  into 
halves.  The  tangent  of  the  angle  made  by  the  last  line  with 
the  horizontal  axis  XX  (any  distance  ypt  divided  by  xp)  is  the 
index  of  correlation. 

A  more  precise  method  is  given  by  Pearson  as  follows: 
Sum  of  products  (deviation  subj.  class  X  deviation  each  iissoc. 

rel.  class  X  no.  of  cases  in  both) 

total  no.  oFludivs.  X  Stand.  Dey.  of  subject  x  Stand.  Dev. 
of  relative ; 

or,  expressed  in  a  formula  : 

^(dev.  x  X  dev.  y  X  /) 
n<Ti<r2 

This  method  requires  finding  many  products  in  the  numera- 
tor, as  many  sets  of  products  as  there  are  entries  in  the  body  of 
the  correlation  table.  A  portion  of  the  products  to  be  found 
in  correlation  table,  p.  43,  is  indicated  below:

COEKELATED   VARIABILITY.  45 

The  handling  of  long  decimal  fractions  may  be  avoided  by 
the  use  of  a  method  similar  to  that  used  at  page  26  for  find- 
ing the  average  and  standard  deviation.  The  formula  for  r 
may  be  written 


Assuming  the  class  including  or  nearest  to  the  true  mean 
of  the  subject  values  as  the  mean  of  the  subjects,  and  the 
class  including  or  nearest  to  the  true  mean  of  the  relative 
values  as  the  mean  of  the  relatives,  find  for  each  variate  the 
product  of  its  deviations  x'  and  y'  from  the  respective  assumed 
means,  and  (having  regard  for  signs)  find  the  algebraic  sum 
of  these  products.  Divide  this  sum  by  the  number  of  vari- 
ates;  the  quotient  is  the  average  of  the  deviation  products  about 
the  assumed  axes.  To  refer  to  the  true  axes,  passing  through 
the  true  means,  find  the  average  moments,  i^  (as  on  page  26), 
both  for  the  subject  and  the  relative  distributions  about  their 
respective  assumed  means,  and  subtract  the  product  of  the 
two  values  of  vl  from  the  average  of  the  approximate  devia- 
tion products  already  found.  Divide  the  difference  by  the 
product  of  the  standard  deviations  of  the  two  frequency  dis- 
tributions. (Compare  Yule,  '97b,  pp.  12-17.) 

The  probable  error  of  the  determination  of  r  is 

=  0.6745(1 -r2)

THE  QUANTITATIVE  TREATMENT  OF  CHARACTERS  NOT  QUAN- 
TITATIVELY MEASURABLE. 

Even  qualities  that  do  not  lend  themselves  to  a  quanti- 
tative expression  may  be  expressed  in  a  roughly  quantitative 
fashion.  The  fundamental  assumption  is  made  that  the 
frequencies  would  obey  the  normal  law  of  frequency  more 
or  less  closely,  provided  a  quantitative  scale  could  be  found. 
This  assumption  will  not,  in  most  biological  data,  lead  us  far 
astray. 

Divide  the  data  into  three  classes  (e.g.,  in  eye-color  we  may 
have  black,  brown  and  gray,  and  blue),  and  let  the  frequency 
of  these  classes  be  n,,  n2,  n3,  in  which  rat  and  n3  are  each  less 
than  %n,  so  that  n2  contains  the  median.  Let  Llt  L.+  be  the 
(unknown)  distances  of  the  mean  from  the  two  boundaries 
of  n2.  Call  Li/a=ht  and  Ls/a=/i3,  then

STATISTICAL    METHODS. 


Now  the  left-hand  side  in  these  equations  is  known ;    it  is  \a 
of  Table  IV.     From  this  table  the  right-hand  value  of  the 


FIG.  11. 

equations  is  found;  it  is  the  entry  corresponding  to  the  argu- 
ment Ja.  Thus  /ij  and  7t3  I  = —  J  are  found,  and  hence  L^/a 

and  Lz/a  and  the  entire  range  — of  the  middle  class, 

in  terms  of  a,  is  known.  Call  the  range  in  absolute  units  I. 
Then  Z=Z/3  +  I/1  and  I/ 'a  is  known  and  for  a  second  series  I/ a* 
can  be  similarly  determined.  Hence  a/a',  the  ratio  of  the 
variabilities  of  the  two  series,  is  determined. 

Again,  since  LJa  and  — —  -1  are  known,  ^/(Z/g  +  Z/j)  is 

known,  and  this  gives  us  the  ratio  in  which  the  mean  divides 
the  true  range  of  the  central  class.  (Pearson  and  Lee,  1900.) 
The  foregoing  method  may  sometimes  be  advantageously 
employed  where  the  data  are  quantitative.  In  this  case 
the  numerical  value  of  I  is  known.  (Macdonell,  1902.)

THE  CORRELATION  OF  NON-QUANTITATIVE  QUALITIES. 

Pearson  (1900C)  has  ingeniously  discovered  a  method  of  ex- 
pressing correlation  quantitatively  when  the  variables  cannot 
be  so  expressed,  as,  for  example,  in  the  case  of  effectiveness 
of  vaccination.  Strictly,  this  method  assumes  normal  vari- 
ation in  variables,  but  it  can  be  employed  generally,  in 
default  of  a  better  method,  with  fairly  accurate  results. 

The  prime  requisite  is  that  the  qualities  to  be  compared 
shall  be  separable  into  two  grades,  an  upper  and  a  lower. 
For  example,  in  the  case  of  the  result  of  vaccination:  on 
the  one  hand,  either  presence  or  absence  of  a  scar;  on 
the  other,  either  recovery  or  death.  As  either  of  the 
second  pair  may  occur  with  either  of  the  first  pair,  four 
classes,  a,  b,  c,  d,  will  be  formed  altogether  and  a  correlation 
surface  like  the  following  may  be  made: 


a

of  which  the  values  may  be  looked  up  in  Table  III,  or,  better, 
their  product  may  be  calculated  by  logarithms  as  follows: 


Find  also  log  hk,  h2,  and  k2.      To  find  r  solve  the  following 
equation  to  as  many  terms  as  may  be  necessary: 


(/i4  -  67i2  +  3)  (A;4  -  GF  +  3)r5 


+-_Lhk(h*-  lOh2  + "15)  (k4  -  lOfc2  +  15)r6  +  etc. 


This  gives  us  a  numerical  equation  of  the  nth  degree  which 
can  be  solved  by  ordinary  algebraic  methods,  using  Sturm's 
functions  and  Horner's  method.  Or  it  can  be  solved  by 
successive  approximations  as  follows:  The  first  approxima- 
tion is  made  by  neglecting  all  powers  of  r  above  the  second 
and  solving  the  quadratic  (remembering,  that  if  ax2  +  bx  +  c  =  0,

n  I ,  and  taking  the  positive  root.     Substi- 

tute this  value  in  the  whole  equation  to  the  4th  power  for 
/(r),  and  in  the  first  derivative  of  the  same  equation  for  /'(r) 
(remembering  that  the  first  derivative  of  /(#)  is  obtained  by 
multiplying  each  term  in  /(x)  by  the  exponent  of  x  in  that 
term  and  diminishing  the  exponent  of  x  by  1).  The  correc- 
tion 7774  should  be  added  to  the  value  of  r  used  in  substi- 
f  (r) 

tuting.     Repeat  this  process  as  often  as  the  correction  affects 
the  fourth  place  of  decimals,  and  go  to  r5  if  necessary. 
The    probable    error    of  r  as  thus   determined   is 

found  as  follows:   First  calculate  the  relations  &=  — '- 


fr  —  rh 

and  /?2  =  —  ^=.     Also  find

foregoing  formula,  it  must  be  noted  that  "a  is  the  quadrant 
in  which  the  mean  falls,  so  that  h  and  k  are  both  positive." 
In  other  words,  a  +  c  >  b  +  d  and  a  +  b  >  c  +  d.  (Pearson,  J00C.)

It  was  desired  to  determine  the  correlation  between  the  eye-color 
of  the  offspring  and  that  of  their  great-grandparents  Clearly  the 
ranges  of  the  classes  given  above  are  not  quantitatively  equal  nor 
determinable  Consequently  a  fourfold  table  was  formed  by  dividing 
the  population  into  those  having  eyes  whose  color  was  gray  blue-green, 
or  lighter,  and  those  having  dark  gray,  hazel,  or  darker  eyes.  This 
gives  a  good  basis  for  calculation  If  the  dark  gray  and  hazel  eyes 
had  been  grouped  with  the  lighter  eyes  it  would  have  made  quadrant 
a  entirely  too  large;  and  there  is  nothing  in  the  nature  of  the  data 
that  strongly  favors  one  division  more  than  another

QUICK  METHODS  OF  ROUGHLY   DETERMINING  THE  COEFFI- 
CIENT OF  CORRELATION. 

The  method  just  described  may  be  used  in  lieu  of  the  rela-

tion  r=      1  l  whenever  the  distributions  of  frequencies  of 

fUFjtfj 

the  two  correlated  organs  are  normal.  An  exceedingly  sim- 
ple relation  that  is  independent  of  the  assumption  of  a  normal 
distribution  has  been  given  by  Yule  ('00b)  as 

ad  —  be 


and  this  may  be  used  as  a  rough  approximation  to  the  coeffi- 
cient of  correlation. 

But  Pearson  ('00C)  has  shown  that  this  simple  relation  is 
not  nearly  as  close  to  the  true  r  as  the  following:

The  superiority  of  the  value  rs  as  an  approximation  to  r, 
justifies  the  additional  work  its  determination  demands. 

SPURIOUS  CORRELATION  IN  INDICES. 

When  two  characters  a  and  b  are  measured  in  each  indi- 
vidual of  a  series  of  individuals,  and  each  absolute  magnitude 
is  transformed  into  an  index  by  dividing  it  by  the  magnitude 
of  a  third  character  c  as  found  in  the  same  individuals,  a 
spurious  correlation  will  be  found  to  exist  between  the  indices 

of  —  and  —  (Pearson,  J97).

CORRELATED    VARIABILITY.  55 

The  precise  method  of  using  r0  in  modifying  any  determi- 
nation of  r  is  uncertain.  Pearson  recommends  using  r  — r0 
as  the  true  measure  of  " organic  correlation"  in  the  case  of 
indices. 

HEREDITY. 

Heredity  is  a  certain  degree  of  correlation  between  the 
abmodality  of  parent  and  offspring.  The  statistical  laws  of 
heredity  deal  not  with  relations  between  one  descendant  and 
its  parent  or  parents,  but  only  with  mean  progeny  of 
parents.  Any  group  of  selected  parents  is  called  a  parentage, 
the  progeny  of  a  parentage  is  called  a  fraternity. 

Three  categories  of  inheritance  have  long  been  recognized 
(Galton,  1888,  p.  12).  These  are:  (1)  blending  heritage  illus- 
trated by  stature  in  man;  (2)  alternative  heritage,  illustrated 
by  human  eye-color;  and  (3)  mixed  heritage,  illustrated  by 
the  piebald  condition  of  the  progeny  of  mice  of  different 
colors.  The  immediately  following  statistical  laws  of  inherit- 
ance hold  especially  for  blending  heritage. 

In  miiparental  inheritance,  as  in  budding  or  asexual 
generation,  heredity  of  any  character  is  measured  by  the  coef- 
ficient of  correlation  between  the  abmodality  in  a  parentage 
and  the  abmodality  of  the  corresponding  fraternity.  More 
strictly,  since  the  variability  of  the  character  in  the  second 
generation,  <r2,  may  (as  a  result  of  selection  or  of  environ- 
mental change)  be  different  from  the  variability  of  the  char- 
acter in  the  first  generation,  alt  the  index  should  be  taken  as 

r— ,  called  the  coefficient  of  regression. 

The  probable   error  of  this  determination   is 

.6745(7,.  /I  -r122    . 

~\/ *-)  m  which  r12  means  the  correlation  coeffi- 
cient between  the  filial  character  and  that  of  the  single  parent 
under  consideration. 

The  variability  of  the  fraternity  is  to  variability  of  offspring 
in  general  as\/l— r2  is  to  1. 

In  bipareiital  inheritance,  if  there  is  no  evidence  of 
fissortative  mating,  or  rorrolation  between  the  two  parents  in 
the  character  in  question,  the  mean  abmodality  of  any  f rater-

where  7^  =  average  abmodality  of  fraternity; 

h2=  average  abmodality  of  male  parent; 

^3=  average  abmodality  of  female  parent; 

r2=  correlation    coefficient    between    fraternity    and 

female  parent; 
rz=  correlation  coefficient  between  fraternity  and  male 

parent; 

GI=  standard  deviation  of  fraternity; 
<72=  standard  deviation  of  male  parent; 
<73=  standard  deviation  of  female  parent. 
When  assortative  mating  occurs,  as  is  usually  the  case,  the 
abmodality  of  a  fraternity  is  given  by 


where   ^  =  correlation    between    male    and   female    parents. 
The  other  letters  have  the  same  signification  as  before. 

The  strength  of  heredity  in  assortative  mating  is  measured 
by  the  formula 


To  find  the  coefficient  of  correlation  between 
brethren  from  the  means  of  the  arrays. 

This  is  given  by  the  formula 


where  nv  is  the  number  of  the  brethren  in  an  array  [and  there- 
fore JWiCwj  —  1)  is  the  number  of  possible  pairs  of  brothers  in 
that  array];  Al  is  the  mean  value  of  the  array;  a  is  the 
standard  deviation  of  the  character  in  the  brethren  taken 
all  together,  n  is  the  total  number  of  variates,  and  A2  is  the 
average  of  the  brethren.  This  method  will  be  found  useful 
where  to  take  all  possible  pairs  of  brethren  would  be  founc? 
a  work  of  too  great  magnitude  (Pearson,  Lee,  etc./99,  p.  271). 


CORRELATED    VARIABILITY.  57 

Galtoii  ('97)  has  shown  that  an  individual  inherits  not  only 
from  his  parents,  but  also  from  his  grandparents,  great-grand- 
parents, and  so  on.  The  heritage  from  his  2  parents  together 
is,  011  the  average,  50$  or  i  of  the  whole  ;  from  the  4  grand- 
parents 25#  or  J  ;  from  the  8  great-grandparents  12.  5#  or  £; 

from  the  nth  ancestral  generation  —  of  the  whole  ;  the  total 

heritage  adding  up  100#.     This  law  has  been  generalized  by 
Pearson  ('98)  as  follows  : 


where  hi   =  average  abmodality  of  fraternity. 
CTO  =  standard  deviation  of  fraternity. 
<TI  ,  cr,  .  .  .  <T8  =  standard  deviation  of  mid-parent  of 
1st,  2d  ...  «th  ancestral  generation. 
A?i  =  abmodality  of  mid-parent  of  1st  ancestral  genera- 

tion. 
&a,  k*  .  ,  .  ka  =  abmodality  of  mid-parent  of  2d,   3d 

.  .  .  sth  ancestral  generation. 

The  abmodality  of  the  mid-parent  of  any  degree  of  ancestry 
may  be  taken  as  the  average  abmodality  of  all  the  contributory 
ancestors  of  that  generation. 

MENDEL'S  LAW  OF  ALTERNATIVE  INHERITANCE. 

In  1865  Georg  Mendel  published  an  account  of  his  experi- 
ments in  Plant  Hybridization  and  reached  the  following  laws, 
which  'have  been  abundantly  confirmed  in  certain  experi- 
ments. 

First  Case.  The  two  parents  differ  in  one  character  (the 
antagonistic  peculiarity)  —  case  of  monohybrids. 

Of  the  two  antagonistic  peculiarities  the  cross  exhibits 
only  one;  and  it  exhibits  it  completely,  so  as  not  to  be  dis- 
tinguishable in  this  regard  from  one  of  the  parents.  Inter- 
mediate conditions  do  not  occur  [in  alternative  heritage]. 

2.  In  the  formation  of  the  pollen  and  the  egg-cell  the  two 
antagonistic  peculiarities  are  segregated;  so  that  each  ripe 
germ-cell  carries  only  one  of  these  peculiarities. 


58  STATISTICAL   METHODS. 

Of  the  two  antagonistic  peculiarities  united  in  the  cross, 
that  which  becomes  visible  in  the  soma  is  called  by  Mendel  the 
dominating,  that  which  lies  latent  is  called  the  recessive  char- 
acter. What  determines  which  character  shall  be  dominating 
is  still  unknown,  and  the  determination  of  this  point  offers  an 
enticing  field  of  inquiry.  In  some  cases  the  dominating  form 
is  the  systematically  higher,  in  others  it  is  the  older  or  ances- 
tral form. 

The  law  of  dichotomy  may  now  be  developed.  When  a 
mongrel  (monohybrid)  fertilization  takes  place  the  zygote  con- 
tains both  the  dominant  quality  (abbreviated  d)  and  the  re- 
cessive quality  (r).  In  the  early  cleavages  d  and  r  are  both 
passed  over  into  both  the  daughter-cells;  but  apparently,  at 
the  time  of  segregation  of  the  germ-cells,  the  somatic  cells 
are  provided  with  d  only,  while  the  germ-cells  retain  both 
qualities.  In  the  ripening  of  these  germ-cells,  probably  in 
the/ reduction  division,  d  and  r  come  to  reside  in  distinct  cells, 
so  that  we  have 

of  the  female  cells  50%d+50%r,  and 
of  the  male  cells     50%d  +  50%r. 

If  now  mongrels  are  crossed  haphazard,  a  male  d  cell  may 
unite  with  either  a  female  d  cell  or  with  a  female  r  cell;  like- 
wise a  male  r  cell  may  unite  with  a  female  d  or  a  female  r  cell. 
Consequently  in  the  long  run  we  shall  have  of  all  the  zygotes 

25%d,  d  +  50%d,  r  +  25%r,  r, 

or  50%  of  the  zygotes  hybrid  and  50%  of  pure  blood,  dnd  of 
the  latter  half  exclusively  maternal  and  half  paternal.  But 
since  the  soma  developed  from  the  hybrid  germ-cell  has  the 
dominant  character,  we  shall  have 

75%  of  the  cases  with  the  dominant  character; 
25%  "    "       "        "      M    recessive 

and  this  agrees  with  various  empirical  results,  of  which  the 
following  from  Correns  is  instructive.  A  cross  was  obtained 
between  a  variety  of  pea  with  a  green  (g)  germ  and  one  having 
a  yellow  (y)  germ.  Yellow  is  dominating.

31  y  (hybrid)  peas  produced  12  plants; 
these  bore:

(hybrid  +  y)         (pure-blooded) 
peas  (=76.4%)    peas  (-23.6%) 


It  is  clear  that  if  this  process  of  crossing  of  the  hybrids 
continues,  the  proportion  of  hybrids  to  the  whole  population 
will  diminish;  for  the  share  of  pure-blooded  forms  breeds 
true;  while  the  originally  equal  share  of  hybrids  is  repeatedly 
halved. 

If  the  hybrid  is  crossed  with  one  of  the  parents  instead  of 
with  another  hybrid,  we  will  get 

(1)  (d+r)d=d,  d+d,  r,      and 

(2)  (d  +  r)r=d,  r+r,r. 

in  (1)  all  of  the  progeny  will  appear  of  the  dominant  type. 
In  (2)  one-half  will  appear  of  that  type.  This  again  agrees 
with  experiment. 

Second  Case.  The  two  parents  differ  in  respect  to  two 
characters — case  of  dihybrids.  Imagine  a  lot  of  ripe  germ- 
cells  with  the  antagonistic  qualities  of  any  pair  separated 
according  to  the  second  principle  stated  at  the  outset.  A 
indicates  the  one  pair  of  qualities  and  B  the  other;  then  we 
shall  have  nine  classes  of  zygotes,  the  proportion  of  each  of 
which  is  as  follows: 

A.  25%d,d 


B.     G.25%d,  d;  12.5%J,  r;  6.25%r,  r. 
A. 


B.     I2.5%d,  d;  25%d,  r;  12.5%r,  r. 
A.  25%r,  r 


B.     6.25%d,d',  12.5%d,r]  6.25%r,  r. 


60  STATISTICAL   METHODS. 

Thus  the  first  class  has  6.25%  purely  dominant  in  both 
characters;  the  second  class,  12.5%  purely  dominant  in  one 
character  and  hybrid  in  the  other,  and  so  on.  Recalling  that 
hybrid  zygotes  produce  somas  with  the  dominant  character, 
it  follows  that  the  progeny  appear  as  follows: 

Ratios 
A.  dom.  +  B.  rec  ...........   18.75%         3 

A.  rec.    +B.  dom  ..........   18.75%         3 

A.  dom.  +  B.  dom  ..........   56.  25%         9 

A.  rec.    +B.  rec  ...........     6.25%         1 

This  result  again  agrees  with  experiment.  The  resulting 
mixture  of  characters  in  tri-  to  poly  hybrids  may  be  likewise 
predicted,  by  extending  the  principles  already  laid  down. 

MEASURE  OF  DISSYMMETRY  IN  ORGANISMS. 

A  Dissymmetry-Index,  3,  measuring  the  average  de- 
gree of  asymmetry  in  the  right  and  left  organs  of  bilateral 
organisms,  has  been  proposed  by  Duncker  (1903). 

First  a  series  of  integral  differences  —3,  —2,  —1,  0,  1,  2, 
3,  4,  etc.,  between  the  right-  and  left-side  measurements  of 
the  organ  in  question  is  made,  and  the  frequencies  of  each 
integral  difference  (reckoning  to  the  nearest  integer)  is  found. 
The  average  of  the  difference  series  is  the  difference  of  the 
averages  of  the  right-  and  left-side  measurements,  and  the 
standard  deviation  of  the  difference  is  given  by 


in  which  the  subscripts,  refer  to  the  bilateral  series  of  which 
the  asymmetry  is  to  be  found,  and  r  is  the  coefficient  of  'cor- 
relation between  the  two  sides. 

Let  df  represent  any  positive  differences  in  the  series,  and 
d"  any  negative  differences;  and  let  //,  //,  etc.,  represent 
the  frequencies  of  the  negative-difference,  classes,  and  //', 
//',  etc.,  the  frequencies  of  the  positive-difference  classes 
Then  the  asymmetry-index

CHAPTER  V. 
SOME  RESULTS  OF  STATISTICAL  BIOLOGICAL  STUDY. 

It  is  hoped  that  the  following  analysis  of  the  literature, 
although  not  complete,  will  prove  suggestive  and  otherwise 
useful.  Numerical  results  are  occasionally  given.  These  are 
intended  to  be  used  in  making  comparisons  with  numerical 
results  obtained  in  the  same  field  and  thus  to  assist  in  the 
interpretation  of  such  results.  The  literature  references  are 
to  the  Bibliography  which  follows  this  chapter,  in  which  the

row, Bumpus,  '99;  percentage  death-rate  of  families  of 
Aphids  has  inverse  correlation  with  length  of  antenna  of 
mother  (r=  —.201  ±.084),  with  frontal  breadth  of  mother 
(r=  —  .184  ±.084),  and  with  number  in  newly  born  brood

In  the  example,  the  data  of  which  are  given  on  p.  26,  the 
frequency  between  the  limits  is  given  in  %  column.  The  —  of 

G 

each  limit  (as  an  inner  class  limit)  is  found  and  the  entries 
in  Table  IV  corresponding  to  the  limits  are  taken.  Each 
such  entry  is  subtracted  from  0.50000,  *Js  multiplied  by 
100,  and  from  the  product  is  subtracted  the  total  theoretical 
percentage  of  variates  lying  between  the  outer  limit  of  the 
class  and  the  corresponding  extremity  of  the  half  curve. 
This  gives  the  theoretical  frequency  of  the  class  in  question. 
The  closeness  of  agreement  of  the  last  column  with  the 
"Percent."  column  indicates  the  closeness  of  the  observed 
frequency  to  the  theoretical. 

V.  Table  of  log  T  functions  of  p.  This  table 
will  enable  one  to  solve  the  equations  for  yQ  given  on  page  32. 
The  table  gives  the  logarithms  of  the  values  of  F  functions 
only  within  the  range  p  —  1  to  2.  As  all  values  of  the  func- 
tion within  these  limits  are  less  than  1,  the  mantissa  of  the 
logarithms  is  —  1;  but  it  is  given  in  the  table  as  10  —  1  =  9, 
as  is  usually  done  in  logarithmic  tables. 

Supposing  the  quantity  of  which  we  wish  to  find  the  value 
reduced  to  the  form  r(4.273).  The  value  cannot  be  found 
directly  because  the  value  of  p  is  larger  than  the  numbers  in 
the  table  (1  to  2).  The  solution  is  made  by  aid  of  the  equation 
r(p  +  l)=pF(p),  thus: 

log  r(1.273)  =  9.955185 
log      1.273  =0.104828 

log  T(3.273)  =  0.060013 
log     2.273  =0.356599 

log  r(3.273)  =  0.416612 
log     3.273  =0.514946 

log  T(4. 273)  =  0.931558 

or,  more  briefly,  log  r(1.273)  =  9.955185 
log  1.273  =  .104828 
log  2.273  =  .356599 
log  3.273  =  .514946 

log  T(4.273)  =  0.931558  =  log  8.542

VI.  Table  of  reduction  from  the  common  to 
the  metric  system.  This  is  given  first  for  whole  inches 
from  1  to  99  excepting  even  tens,  which  may  be  got  from  the 
first  line  of  figures  by  shifting  the  decimal  point  one  place 
to  the  right.  The  table  may  be  used  for  huudredths  of  an 
inch  by  shifting  the  decimal  point  two  places  to  the  left. 
Other  fractious  than  decimals  are  given  in  the  lower  tables.

is  easily  constructed,  and  for  large  values  of  n  is  accurate 
with  interpolation  by  inspection  to  two  significant  figures, 
which  are  all  that  are  required. 

X.  Squares,  cubes,  square  roots,   and  recip- 
rocals  of  numbers  from    1  to  1O54.    The  use  of 
this  table  can  be  extended  by  using  the  principle  that  if  any 
number  be  multiplied  by  n,  its  square  is  multiplied  by  n2,  its 

cube  by  n3,  and  its  reciprocal  by  — . 

XI.  Logarithms    of   numbers    to    six    places. 

The  following  explanation  of  the  use  of  the  logarithmic  tables 
is  taken  from  Searles'  Field  Engineering,  pp.  257-263  [ed. 
1887]. 

The  logarithm  of  a  number  consists  of  two  parts, 
a  whole  number,  called  the  characteristic,  and  a  decimal, 
called  the  mantissa.  All  numbers  which  consist  of  the 
same  figures  standing  in  the  same  order  have  the  same  man- 
tissa, regardless  of  the  position  of  the  decimal  point  in  the 
number,  or  of  the  number  of  ciphers  which  precede  or  follow 
the  significant  figures  of  the  number.  The  value  of  the  char- 
acteristic depends  entirely  on  the  position  of  the  decimal  point 


108  STATISTICAL   METHODS. 

in  the  number.  It  is  always  one  less  than  the  number  of 
figures  in  the  number  to  the  left  of  the  decimal  point.  The 
value  is  therefore  diminished  by  one  every  time  the  decimal 
point  of  the  number  is  removed  one  place  to  the  left,  and  vice 
versa.  Thus 

Number.  Logarithm. 

13840.  4.141136 

1384.0  3.141136

.1384  —1.141136 

.01384  —2.141136 

.001384  —3.141136 

etc.  etc. 

The  mantissa  is  always  positive  even  when  the  characteristic 
is  negative.  We  may  avoid  the  use  of  a  negative  characteristic 
by  arbitrarily  adding  ID,  which  may  be  neglected  at  the  closf 
of  the  calculation.  By  this  rule  we  have

.1384  9.141136 

.01384  8.141136 

.001384  7.141136 

etc,  etc. 

No  confusion  need  arise  from  this  method  in  finding  a  number 
from  its  logarithm;  for  although  the  logarithm  6.141136  repre- 
sents either  the  number  1,384,000,  or  the  decimal  .0001384,  yet 
these  are  so  diverse  in  their  values  that  we  can  never  be  uncer- 
tain in  a  given  problem  which  to  adopt. 

TABLE  XI,  contains  the  mantissas  of  logarithms,  car- 
ried to  six  places  of  decimals,  for  numbers  between  1  and  9999, 
inclusive.  The  first  three  figures  of  a  number  are  given  in  the 
first  column,  the  fourth  at  the  top  of  the  other  columns.  The 
first  two  figures  of  the  mantissa  are  given  only  in  the  second 
column,  but  these  are  understood  to  apply  to  the  remaining 
four  figures  in  either  column  following,  which  are  comprised 
between  the  same  horizontal  lines  with  the  two. 

If  a  number  (after  cutting  off  the  ciphers  at  either  end)  con- 
sists of  not  more  than  four  figures,  the  mantissa  may  be  taken 
direct  from  the  table ;  but  by  interpolation  the  logarithm  of  a 
number  having  six  figures  may  be  obtained.  The  last  column 
contains  the  average  difference  of  consecutive  logarithms  on 


EXPLANATION   OF   TABLES.  109 

the  same  line,  but  for  a  given  case  the  difference  needs  to  be 
verified  by  actual  subtraction,  at  least  so  far  as  the  last  figure 
is  concerned.  The  lower  part  of  the  page  contains  a  complete 
list  of  differences,  with  their  multiples  divided  by  10. 

To  find  the  logarithm  of  a  number  having  six 
figures  :— Take  out  the  mantissa  for  the  four  superior  places 
directly  from  the  table,  and  find  the  difference  between  this 
mantissa  and  the  next  greater  in  the  table.  Add  to  the  man- 
tissa taken  out  the  quantity  found  in  the  table  of  proportional 
parts,  opposite  the  difference,  and  in  the  column  headed  by  the 
fifth  figure  of  the  number;  also  add  ^  the  quantity  in  the  col- 
umn headed  by  the  sixth  figure.  The  sum  is  the  mantissa 
required,  to  which  must  be  prefixed  a  decimal  point  and  the 
proper  characteristic. 

Example.—  Find  the  log  of  23.4275. 

For  2342  mantissa  is  369587

Am.  For  23.4275  log  is    1.369726 

The  decimals  of  the  corrections  are  added  together  to  deter- 
mine the  nearest  value  of  the  sixth  figure  of  the  mantissa. 

To  find  the  number  corresponding  to  a  given 
logarithm. — If  the  given  mantissa  is  not  in  the  table  find  the 
one  next  less,  and  take  out  the  four  figures  corresponding  to  it ; 
divide  the  difference  between  the  two  mantissas  by  the  tabu- 
lar difference  in  that  part  of  the  table,  and  annex  the  figures  of 
the  quotient  to  the  four  figures  already  taken  out.  Finally, 
place  the  decimal  point  according  to  the  rule  for  characteristics, 
prefixing  or  annexing  ciphers  if  necessary.  The  division  re- 
quired is  facilitated  by  the  table  of  proportional  parts,  \vhich 
furnishes  by  inspection  the  figures  of  the  quotient.

110  STATISTICAL   METHODS. 

The  number  derived  from  a  six-place  logarithm  is  not 
reliable  beyond  the  sixth  figure. 

At  the  end  of  Table  XI  is  a  small  table  of  logarithms  of 
numbers  from  1  to  100,  with  the  characteristic  prefixed,  for 
easy  reference  when  the  given  number  does  not  -exceed  two 
digits.  But  the  same  mantissas  may  be  found  in  the  larger 
table. 

TABLE  XII. — The  logarithmic  sine,  tangent,  etc., 
of  an  arc  is  the  logarithm  of  the  natural  sine,  tangent,  etc.,  of 
the  same  arc,  but  with  10  added  to  the  characteristic  to  avoid 
negatives.  This  table  gives  log  sines,  tangents,  cosines,  and 
cotangents  for  every  minute  of  the  quadrant.  With  the 
number  of  degrees  at  the  left  side  of  the  page  are  to  be  read 
the  minutes  in  the  left-hand  column;  with  the  degrees  on 
the  right-hand  side  are  to  be  read  the  minutes  in  the  right-hand 
column.  When  the  degrees  appear  at  the  top  of  the  page  the 
top  headings  must  be  observed,  when  at  the  bottom  those  at 
the  bottom.  Since  the  values  found  for  arcs  in  the  first  quad- 
rant are  duplicated  in  the  second,  the  degrees  are  given  from 
0°  to  180°.  The  differences  in  the  logarithms  due  to  a  change 
of  one  second  in  the  arc  are  given  in  adjoining  columns. 

To  find  the  log.  sin,  cos,  tan,  or  cot  of  a  given 
arc. :  Take  out  from  the  proper  column  of  the  table  the  log- 
arithm corresponding  to  the  given  number  of  degrees  and 
minutes.  If  there  be  any  seconds  multiply  them  by  the  ad- 
joining tabular  difference,  and  apply  their  product  as  a  cor- 
rection to  the  logarithm  already  taken  out.  The  correction  is 
to  be  added  if  the  logarithms  of  the  table  are  increasing  with 
the  angle,  or  subtracted  if  they  are  decreasing  as  the  angle  in- 
creases. In  the  first  quadrant  the  log  sines  and  tangents  in- 
crease, and  the  log.  cosines  and  cotangents  decrease  as  the 
angle  increases.

EXPLANATION    OF    TABLES.  Ill 

To  find  the  angle  or  arc  corresponding  to  a 
given  logarithmic  sine,  tangent,  cosine,  or  co- 
tangent.— If  the  given  logarithm  is  found  in  the  proper 
column  take  out  the  degrees  and  minutes  directly;  if  not,  find 
the  two  consecutive  logarithms  between  which  the  given 
logarithm  would  fall,  and  adopt  that  one  which  corresponds  to 
the  least  number  of  minutes;  which  minutes  take  out  with  the 
degrees,  and  divide  the  difference  between  this  logarithm  and 
the  given  one  by  the  adjoining  tabular  difference  for  a  quo- 
tient, which  will  be  the  required  number  of  seconds. 

With  logarithms  to  six  places  of  decimals  the  quotient  is 
not  reliable  beyond  the  tenth  of  a  second. 

Example.—  9.383731  is  the  log  tan  of  what  angle?

The  above  rules  do  not  apply  to  the  first  two  pages  of  this 
table  (except  for  the  column  headed  cosine  at  top)  because 
here  the  differences  vary  so  rapidly  that  interpolation  made  by 
them  in  the  usual  way  will  not  give  exact  results. 

On  the  first  two  pages,  the  first  column  contains  the  number 
of  seconds  for  every  minute  from  1'  to  2° ;  the  minutes  are 
given  in  the  second,  the  log.  sin.  in  the  third,  and  in  thefourfo 
are  the  last  three  figures  of  a  logarithm  which  is  the  difference 
between  the  log  sin  and  the  logarithm  of  the  number  of  sec 
onds  in  the  first  column.  The  first  three  figures  and  the  char- 
acteristic of  this  logarithm  are  placed,  once  for  all,  at  the  head 
of  the  column. 

To  find  the  log  sin  of  an  arc  less  than  2°  given 
to  seconds. — Reduce  the  given  arc  to  seconds,  and  take  the 
logarithm  of  the  number  of  seconds  from  the  table  of  loga- 
rithms, and  add  to  this  the  logarithm  from  the  fourth  column 
opposite  the  same  number  of  seconds.  The  sum  is  the  log  sin 
required. 


112  STATISTICAL    METHODS. 

The  logarithm  in  the  fourth  column  may  need  a  slight  inter- 
polation of  the  last  figure,  to  make  it  correspond  closely  to  the 
given  number  of  seconds. 

Example.— Find  the  log  sm  of  1°  39'  14". 4.

Log  tangents  of  small  arcs  are  found  in  the  same  way,  only 
taking  the  last  four  figures  of  (q  -  1)  from  the  fifth  column. 

Example.—  Find  the  log  tan  of  0°  52'  35*. 

52'  35"  =  (3120"  +  35")  =  3155"  log  5.498999

To  find  the  log  cotangent  of  an  angle  less  than 
2°  given  to  seconds. — Take  from  the  column  headed  ( q-\- 1} 
the  logarithm  corresponding  to  the  given  angle,  interpolating 
for  the  last  figure  if  necessary,  and  from  this  subtract  the  loga- 
rithm of  the  number  of  seconds  in  the  given  angle. 

Example.— Find  the  log  cotan  of  1°  44'  22".  5.

These  two  pages  may  be  used  in  the  same  way  when  the 
given  angle  lies  between  88°  and  92°,  or  between  178°  and  180°; 
but  if  the  number  of  degrees  be  found  at  the  bottom  of  the  page, 
the  title  of  each  column  will  be  found  there  also;  and  if  the 
number  of  degrees  be  found  on  the  right  hand  side  of  the  page, 
the  number  of  minutes  must  be  found  in  the  right  hand  col- 
umn, and  since  here  the  minutes  increase  upward,  the  number 
of  seconds  on  the  same  line  in  the  first  column  must  be  dimin- 
ished by  the  odd  seconds  in  the  given  angle  to  obtain  the  num- 
ber whose  logarithm  Is  to  be  used  with  (q±l)  taken  from  the 
table.

Ans.     12.047241 

To  find  the  arc  corresponding1  to  a  given  log 
sin,  cos,  tan,  or  cotan  which  falls  within  the 
limits  of  the  first  two  pages  of  Table  X. 

Find  in  the  proper  column  two  consecutive  logarithms  be- 
tween which  the  given  logarithm  falls.  If  the  title  of  the 
given  function  is  found  at  the  top  of  that  column  read  the 
degrees  from  the  top  of  the  page;  if  at  the  "bottom  read  from 
the  bottom. 

Find  the  value  of  (q  —  1)  or  (g  +  0,  as  the  case  may  require, 
corresponding  to  the  given  log  (interpolating  for  the  last  figure 
if  necessary).  Then  if  q  =  given  log  and  I  =  log  of  number  of 
seconds,  nt  in  the  required  arc,  we  have  at  once  I  =  q  —  (q  —  1} 
or  I  =  (q  + 1)  —  q,  whence  n  is  easily  found. 

Find  in  the  first  column  two  consecutive  quantities  between 
which  the  number  n  falls,  and  if  the  degrees  are  read  from 
the  left  hand  side  of  the  page,  adopt  the  less,  take  out  the 
minutes  from  the  second  column,  and  take  for  the  seconds 
the  difference  between  the  quantity  adopted  and  the  number 
n.  But  if  the  degrees  are  read  from  the  right  hand  side  of  the 
page,  adopt  the  greater  quantity,  take  out  the  minutes  on  the 
same  line  from  the  right-hand  column,  and  for  the  seconds 
take  the  difference  between  the  number  adopted  and  the  num- 
ber n.
